Soul Reaver 2 is a 2001 action-adventure video game developed by Crystal Dynamics and published by Eidos Interactive. It is a sequel to Legacy of Kain: Soul Reaver and the third game in the Legacy of Kain series. Originally developed as a PlayStation and Dreamcast project, it was reworked into a PlayStation 2 and Microsoft Windows title in early production. Soul Reaver 2 was followed by two sequels, Blood Omen 2 and Legacy of Kain: Defiance, in 2002 and 2003. The game continues the adventures of the vampire-turned-wraith Raziel, the protagonist of Soul Reaver. Though Raziel initially seeks to exact revenge on Kain, his murderer and former master, this objective is superseded by a higher quest for knowledge and a desire for freedom, as he finds himself manipulated by those he encounters and begins to learn more about his former life as a human. Traveling through history, he gradually exposes the truth behind his own past and destiny, as he uncovers the history of Nosgoth. Hoping to deliver a more story-focused, cinematic experience than Soul Reaver, Crystal Dynamics researched time travel fiction, theology, and the works of Joseph Campbell when creating Soul Reaver 2's narrative. Critics praised the game for its involved storyline, visuals and puzzles, but criticized it for lacking replay value and ending without a definite resolution. Its developers felt the final product fell short of their ambitions, but it performed well commercially, and was included on Sony's "Greatest Hits" list.
